Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2006 Nissan Altima has a trend of engine problems, both in our data & definitely in the NHTSA's complaint data as well.

Excessive oil consumption is the main problem reported by owners. Nissan did a recall back in 2006 for oil consumption due to bad piston rings, but many owners report to us that the recall didn't fix the problem.

The dealer only had to check the oil consumption rate. Typically 1 qt per 1,000 miles is "acceptable" per OEM standards ... that's a lot of oil!

Upon inspection of my car. And seeing news reports about 2002 to 2006 Nissan Altima. My floors on both sides are fully rotted out. The rest of the car is solid. This is a huge safety issue as ur feet can go thru the floor. I have pictures. Nissan should have a recall or a fix for this...

Nissan is fully aware that many of their makes for several years have transmission issues that are directly related to them, and not the customer. There is (was??) a class action lawsuit against them that met my issues to a T. the transmission began hesitating when going from reverse to drive, and then jerking very hard into gear. Now it rough shifts between gears, and when driving if I slow down and begin to accelerate again it hesitates and almost stops, then the RPM goes up high and jerks very hard into gear. The issue is increasingly getting worse. Nissan should have to take responsibility and pay for their issue, especially when it is effecting hundreds of customers. I have a warranty but they refuse to help me unless my transmission is in pieces on the mechanics floor so they can look at it. The warranty company says it is my responsibility to find the mechanic, authorize the tear down, and then of course pay the bill if they refuse to fix it. This issue is not my fault and I should not be penalized for something I did not do. I chose Nissan expecting quality and so that is not what I have received. I paid my car off in a year (and it wasn't cheap!) so I cannot just go trade it in, and I do not have money to pay another car note. I expected at least 10 years out of the car, and should be able to get far more than 10 years out of it. This is ridiculous. My car is breaking down in front of my eyes with less than 115,000 miles on it and this is supposed to be a quality car. I should not have to be the one to pay these repairs. We are victims and we deserve to be compensated, not be punished.

Floorboards are rusting through on driver & passenger sides of the vehicle. I'm concerned about safety if a hole opens or if something comes through from the underside.

While driving ~25 mph I was slowing down to a red traffic light and my car spontaneously shut off in traffic! I was able to put my car in park and restart the car. A few days later, it took 3 attempts before my engine started. After a diagnostic, the car displayed codes P0335 (crankshaft position sensor) and P0725 (engine speed circuit signal sensor). After doing much research I found hundreds of complaints online with similar issues! I input my VIN# to see if my vehicle was under recall and it wasn't. after seeing hundreds of the same complaints, why hasn't their been a recall" if there was, how is it possible that my car wasn't recalled"

The passenger side floorboard is completely rusted through. The area is approximately 5in by 12in and it seems that it us due to improper drainage from the manufacturing process. Sound dampening material is applied above a drain hole not allowing water to drain out. Now I have concern with the structural integrity of the vehicle since the body is part of the frame....updated 09/28/15

While pulling to a stop light, the car engine shut off without warning. I put the car in park, turned off & attempted to restart the car. It wouldn't immediately start. This happens spontaneously in drive-thrus, stoplights and when coming to complete or near complete stops in traffic as well. Most recently I was exiting the interstate exit and the car stopped as a slowed to turn left off the exit, almost resulting in a car rear ending my vehicle at 50 miles per hou. The ses (service engine soon) light is displayed and even after having an oil change and tune up the light is still illuminated, confirming it's an ongoing issue outside of standard maintenance. I've been provided a reference number and dropped the car at Nissan dealership today to diagnose. Im fearful of my safety operating the vehicle at this point.

While driving my 2006 Altima on 6/8/15 for a few minutes after starting it when it had been parked for more than 12 hours, the car stalled. It restarted and I continued to drive. The following day, this occurred again exactly the same. Then the next day, the car stalled again after the car had been sitting only a few hours and "threw a code", I.e. the "service engine soon" light came on. Today, 6/13/15, it occurred again when driving a few minutes after the car had been sitting for more than 8 hours. This time the car almost wouldn't restart. I looked up this issue and found a recall on the crankshaft position sensor. I took the car to courtesy Nissan who told me that my car did not fall under the recall. After the mechanic diagnosed the problem via the code, it was the crankshaft position sensor.

I took my vehicle in for an oil change and the garage informed me that the floor board on the driver side was rusted out so bad that you could touch the carpet from the bottom. Also the passenger side was rusted with a hole but not as big as the driver side. I am not sure why Nissan has not issued a recall for this being there are hundreds of complaints for this. This problem is a safety issue considering it will not pass a safety inspection.

The floor boards on both the driver and passenger have rooted out almost completely on my 2006 Nissan Altima. I have noticed this a about a year ago and it has got increasingly worse since. I can push the carpet up from under the vehicle and feel very unsafe. I am careful not to put weight on the floors while entering the vehicle for fear I am going to put my foot through the floor. This is a very common issue due to a flawed design in the drain system. The floorboards hold water which may accumulate through the door while raining and salt and water from the under side. Please issue a recall and make Nissan fix these vehicles that could stay on the road for many more years. My car has 109K miles on it and is in very good shape and runs very well. I don't want to have to do this job myself or pay 1,000 to get it fixed.

2006 Nissan Altima sl 3.5 V6, cannot read codes from ECU. Check engine light on, car will take off slow and build up speed almost like it is having a power surge. During driving the gas pedal has to be presses all the way down to gain speed at dangerously slow rates, at times at a full stop the car takes a dangerous amount of time to build up speed.

I noticed a large amount of rust/holes forming under my 06 Nissan Altima with 80K on it. It's all in the floor boards, driver and passenger sides. In first noticed it back in the summer of 2014....a few months after I bought it from a Nissan dealership. They said they couldn't do anything. I saw the news today about the same issue I noticed. We need a recall for safety. Cause it will become one. I will sue if my foot goes thru the floor.

Altima 4-cyl

  • 135,000 miles
The car stalled and completely shut down when coming to a stop at a stop light. Since this time, the car has done this multiple times. The last time this happened, I was driving the car at 25 miles per hour and the car completely shut down. I had to pull over the car in the middle of traffic and restart the car. It almost caused an accident. When we took the car into the Nissan dealership, our 2006 Altima was not covered under the recall.

The floor board on the drivers side is rusted out. About the size of 12"X12".I have checked on line and this seems to be a problem with 2002-2006 Nissan Altima. This is a unsafe issue. Why has Nissan not corrected this problem?this was a issue years ago with cars. The metal must be of very poor quality.

My car has been experiencing pulling since last year. I family member informed me that the problem sounded like the transmission was going bad and that I needed to have the car checked. I took the car to the Nissan dealership and paid for a diagmostic inpsection. The Nissan dealership reported no problems with the engine (which I had to have replaced when the car was purchased brand new) and reported no problem with the transmission. I was told that I needed the brakes and rotors replaced in the front. I got the issue taken care of and the problem stills occurs with my car and it still jerks/pulls when I put my car in drive and am on the road. I think that this is a safety issue that needs to be looked into. I do not believe that the Nissan dealership is being truthful and honest about the situation. When I was there one of the sales reps asked me if I wanted to trade my car in. I could hear the other salesperson/mechanic talk to another person about my car and possible open recalls, but never addressed this with me. I contacted the 1800 number regarding a recall on my car. I was told that there was still a recall open and I explained the problems with my car. The rep told me to take my care in and get it checked again. When I contacted the Nissan dealership the person was short patience with me and told me that I did not need to get it checked because it was already replaced in 2006. I feel like I am driving a car that will eventually break down or fall apart while I am driving. I have put several tires on my car and it seems like I still hear a strange noise coming from the wheels even when I have placed new rotors and brakes on the front and back wheels.

Floor pans on both driver and passenger are rusted with large perforation holes into the cabin of the vehicle. Do not know if vehicle is safe to operate since water visibly enter the car when it rains, and Nissan cannot assure that the seat attached to the car are not compromised by the rusting.

Clutch pedal sinks to the floor board of my Nissan Altima 3.5 SE, the clutch fluid is at full capacity and when the car is in motion at a red light or even at a still motion the clutch goes completely down or out...I have had my fluids checked and it is full....this as been happening since I have owned the car at 52,000 miles and continues to have this problem to this very day.....nissian 3.5 cars are notorious for this problem, but Nissan fails to recognize this as a recall problem....but everyone is having this problem 3.5 - 5 (speeds) with this car and this model.....this is a serious safety issue especially when I am in slowed traffic and cannot shift properly...this issue needs to seriously be addressed and the problem resolved....fatalities should not be their reason to enforce this issue.
